One gigahertz equals 1e+9 hertz. To convert gigahertz to hertz, multiply by 1e+9. To go the other way, multiply hertz by 1e-9. So 5 gigahertz is 5e+9 hertz, 10 is 1e+10 and 100 is 1e+11. Both units measure frequency, so the conversion is a single exact multiplication with no offset — the same factor works in a spreadsheet or in code.
